8800 Tower Control Electronics
The 8800 controller is a state-of-the-art, fully digital dynamic controller that utilizes Instron® core technologies and is capable
of running static and high-frequency dynamic tests. Found at the heart of Instron’s servohydraulic testing systems, the 8800
controller provides full system control, machine safety, transducer conditioning, and data acquisition, as well as acts as the
foundation for the user interface to the testing machine.

Console Software
Console Software is the main user interface to the 8800 controller. Running
on a PC, it allows all controller functions to be viewed and configured including
control-loop optimization, setting of operational limits, and running of simple
cyclic tests. Console provides the foundation for running more demanding
tests in application software such as WaveMatrix™, Bluehill®, or specific
software, such as the Low Cycle Fatigue or Fracture Mechanics suite.

Handset and Power Controls
The handset, power controls. and
emergency stop button make up
the hardware interface that is rigidly
mounted to the testing machine. Their
functionality includes switching the
machine off, into low power or high
power mode; offering coarse or fine
positioning of the actuator; and where
fitted, opening and closing of hydraulic
grips. And when a waveform is running
or when in load control, the handset is
locked from operating.
